BUTTON-SETTING MACHINE.

SPECIFECATION forming part of Letters Patent N o. 688,071, dated December 3, 1901- Application filed January 18. 1901 To all whom t may concern:

Be it known that I, ABEDNEGO Dnwns, a citizen of the United States, and a resident of Brooklyn, in the county of Kings, in the 5 city and State of New York, have invented a certain new and useful Improvement in Button-Setting Machines, of which the following is a full, clear, and exact description, reference being made to the accompanying drawro ings, forming part of this specification.

My invention relates to an improvement in button-setting machines, and more particularly to that kind or class thereof wherein the buttons and the tacks or metal fasteners ting mechanism; and it consists in certain novel features of construction and combinations of parts, as will be hereinafter fully described, and specically pointed ont in the 2o claims.

On the accompanying sheet of drawings, Figure l is a side and sectional elevation of the upper part of a machine embodying the invention; Fig. 2, an edge view ofa fragz 5 ment of the cut-off and a cross-section of the button-chute, and Fig. 3 a front view of the cut-E and a fragment of the chute.

Similar reference-numerals designate like parts in the different views.

3o The object of the invention is to provide the machine to which it is applied with means for feeding'a button into the button-holder at the commencement of each operation instead of during the return movement of the 35 driver or plunger, as it is commonly fed, so that the operator may have plenty of time for the Withdrawal from the button-holder of a button which has been attached to a garment before the next button is allowed to 4o enter the holder.

The frame of the machine shown is'a casting composed of the body l, base l', head 10, and hanger ll. It is fixed on a column 12, to which are attached bearings in which a 45 driving-shaft13 is mounted. Motion is imparted to this shaft from a pulley that is loosely mounted on it and that coacts with a clutch by which the pulley is locked to the shaft to produce an operation of the machine.

5o The clutch is of the ordinary type usually SerielNo.43,7l5. (Nomodel.)

employed in connection with button-setting machines, and as the same is familiar to and well understood by those skilled in the art it is not deemed necessary to illustrate or describe the same in detail, it being sufficient 55 to say that it is engaged with the pulley by pressing on a treadle connected with the clutch and is disengaged from the pulley after a single revolution by a device which forces the pawl or catch of the clutch out of 6o connection with the pulley, so that the shaft makes but a single revolution and then stops and will not be turned another revolution until the clutch is again engaged with the pulley.

In the head l0 ofthe frame is a plunger 2, which is connected by a link with a lever 21, pivoted on a pin 22 to the body l of the frame. A plate 23 is pivoted by a pin 24 to the hanger 1l, and a link 25 connects this 7o plate with the lever 2l, the link being pivoted at its ends to the plate and lever and extending through a hole 12 in the top of the column. Over the frame is a button-reservoir 3, from which a chute extends downward 75 and forward in front of and below the head 10. The movable parts of the button-reservoir are connected with the lever 2l by a rod 3l. A vertically-movable button-holder 4 is secured under the plunger, in front of which 8o it projects, so that buttons may slide into it from the chute 30. It may be attached either to the plunger, as shown, or to a separate slide depending from the frame.

Behind the button-reservoir is a fastener- 85 reservoir 5, from which a chute extends downward and forward to the rivet-holder and whose movable parts are connected with the lever 2l by a rod 5l. The rivet-holder 52 is mounted on a post 53, fixed in the base of 9o the frame and constituting an anvil, on which the fasteners stand when they are upset in the buttons, the rivet-holder loing depressible on the post against the action of a coil-spring (not shown) surrounding the post within the 95 rivet-holder.

The cut-off, to which with its actuating mechanism the invention particularly relates, is shown applied to the button-chute 30. The cut-olf proper is a plate 6, having projections roc and 61 pivoted on the face of the chute, the relations of the projections to the channel of the chute being as shownl in Figs. 2 and 3.l

The plate 6 is connected at its outer end with a lever 62, which is pivoted on a pin 63, fixed in the body 1, the lever fitting at its front end in a round hole in the plate. A bar 64, that extends through the top of the column, is pivoted at its upper end to the rear end of the lever 62 and at its lower end is connectedwith the driving-shaft 13 by a pin 65, which is affixed to the end of the shaft and constitutes with the shaft a crank by which a reciprocating motion is imparted to the bar 64 with each revolution of the shaft. An arm 14 is fixed on the drivingshaft, and at the outer end of this arm is a roller 15, which makes contact with the edge of the plate 23, as indicated in Fig. 1, during part of the revolution of the arm, the roller moving upward and backward from the position in which it is shown.

From the foregoing description it will be understood that when the driving-shaft comes to rest after each revolution the roller 15 is behind and above the plate 23, and as the plunger rises the button, with the garment to which it is attached, is carried up by the button-holder and a fastener is fed into the holder 52, where it remains until the next operation. Afterward the garment is pulled forward by the operator, and the button attached to it is thus drawn out of the button-holder. Then the garment or else another, if another button is not to be attached to the same garment, is laid on the top of the holder 52l and pressure i's applied to the treadle. During the irst part of the revolution of the driving-shaft or before the roller 15 reaches the plate 23 the pin 65 draws downward the bar 64, and with it thel rear end of the lever 62, and the outer end of the plate 6 is raised by the front end of this lever until the projection 6l is moved downward and backward far 'enough to allow the button resting against it descend below the cut-olf, the next button being held back by the projection 60. After the button thus released from the cut-0R gets into the button'- h'older the roller 15 acts on the plate 2 3, fore i'ng upward its rear end, while the link 25 and 'rear :end of the lever 21 are raised and the plunger is driven downward, carrying with it the button-holder and button, the fastener being forced through the garment and upset lin the button. Meanwhile the pin 65 pushes upward the bar 64 and the outer end of the cut-o is depressed by the lever 62, whereupon the lowest button in the chute slides from j the projection 60 tothe projection 6l, on which it rests until the 'cut-olf is 'again actuated, as described, after the button just attached to the "garment has been withdrawn from the 1. In a button-setting machine, the combi;

nation with a vertically-reciprocating plunger and lever for operating the same, of a button-holder below said plunger, a buttonchute extending downward from a reservoir and connecting with said holder, a drivingshaft, a cut-olf applied to the chute and connected with said driving-shaft, and an arm, one end of which is secured to said drivingshaft the opposite end being free, whereby when the driving-shaft is rotated, the free end of said arm indirectly engages with the lever operating said plunger during a part of the rotation of said shaft, substantially as described.
